what version of supersu.zip you flashed ?Thank a lot bro please help me out of a new problem, ur method worked completely fine . I successfully switched from custom to stock rom and then installed the updates available. Now i wanted to root so
I unlocked bootloader using htc dev
Started the phone and all the apps optimized which took around30-40 mins
Now i shifted to bootloader installed twrp then installed supersu which i had already put in extsd
Phone didnt started for an hour stuck on htc screen
Used adb reboot bootloader and repeated everything all again right from fastboot oem lock doing ruu and all still it is same
It works all very fine before installing supersu after that all chaos dont know what to do
